The UNDERSHIRTS, COTTON, SUMMER / COMBAT BATTALION is a lightweight, 6.5oz undershirt originally issued to Marines during World War II.

Often referred to as "Skivvies," our UNDERSHIRTS, COTTON, SUMMER / COMBAT BATTALION is based on the first models introduced at the beginning of the US entry to the second world war which were crafted from white cotton fabric, similar to undershirts worn by the US Navy. It would be in the mid-1940s that the design was updated to a green color to reduce visibility to the enemy. Recognising the need for better camouflage, the USMC issued contracts in 1943 for a unique 'Marine Green' undershirt, specifically tailored for combat in the Pacific theater.
